Building a Low-cost Lightboard for Video Lectures

[@jawsfamily]

I think you can flip a video horizontally in post processing. That would replace the mirror

[@cyxcat9125]

lol

[@MrKsuhiyp]

Jules White should read this

[@RupertBruce]

I presumed that would be the way it was done. Using a mirror is old-school - The intro mentioned Pablo Picasso so I imagine the analog reflection was more feasible than post processing back then!

[@abdalrahman3497]

bring the mirror back to the bathroom

[@eduardocosta9078]

The mirror is useful when you do a live presentation. That´s the case where the post-processing is not possible.

[@alocin110]

I watched several videos on YT, most of them proved to be wok of idiots. I hit your video. Crystal clear commentary, beautiful dressing, blue and black, nice hair style, smiling face, full of energy and lively. You explained everything exceptionally well and professionally. I would say the world is a good place because there are genius, intelligent and brilliant men like you in this world. Great video. I liked it. Thank you very much.

[@timlucas143]

You can pretty easily mirror a live video

[@TwstedTV]

Some cameras allow of reverse video, basically flipping the video live. But they are a bit pricey. ive seen someone do it. but cant recall the type of camera.

[@TriumphAventura]

you can flip live video since the 90s....

[@rahulkapoor8113]

and that velvet jacket is what makes smooth reflection on to the camera

[@MathswhizAustralia]

you could also just do a horizontal flip in any video editing software, so the mirror isn't required. I bought my green screen from ebay for $50 and a giant sheet of perspex (acrylic) from a plastic fabricator for $100. Thanks for sharing this video!

[@GoreGirlFX]

People who don't know anything about video wouldn't think of that. LOL.

[@madnecessity]

5 years later and still relevant Thanks for posting Hope you post stuff again

[@cesar_zapata]

Wow, I went through all of the 73 videos. Although I did not take the time to comment and like each one of them I`d like to say that It was all absolutely amazing. You are such a good speaker. I was having trouble understanding the HTTP pipeline and how spring worked behind the scenes when I came to your chanel. I found all of the content absolutely interesting and helpful. I'm so glad that the programming comunity is always so helpful providing such high quality material to people. I'm looking foward to watching your security videos for android. I don't know what was you motivation to do these videos, in any case a big THANK YOU from Brasil, for taking the time and effort. Take care

[@user-rn5em5zr1y]

Very ingenious indeed! I can't wait to construct it myself. Thank you!

[@spelunkerd]

Cool idea. The hard part for most DIY people is getting a room that doesn't echo, and doesn't reflect light from open windows or other sources of ambient light. Audio is always the most difficult, you seem to have nicely overcome that, too.

[@mohamedabdullahi5708]

I have been searching this vedio for months . Now I understand! Thanks

[@suzannebeers7749]

need more explanation of lighting placement, windows in room, etc. Also tech info suggestions for camera and software would be nice.

[@abhilashpatel3036]

This guy is humble. Very likable persona.

[@toanha6997]

Really like your idea, will make one myself.

[@timhamons]

great sharing!

[@MichaelSturgeon0317]

As someone has mentioned, you don't need to video into a mirror. I use a glassboard and video the professor - then in Premiere I use the effect "horizontal flip" - I tell my colleagues not to wear clothes with words and we will be fine. After doing this for 3 years, I have only had to reshoot one because of the "words on clothes" issue. Try it out -- it is worth avoiding the work-around of using a mirror I am sure. Thanks for your post, BTW.

[@liamnoteworthy5548]

Awesome video... but, if I may make a suggestion, you might want to create more of a contrast between you and the background... like by wearing a lighter colored jacket... it looks like body parts are floating around the screen...

[@AlbAlPasa]

I think it’s even better.

[@AlimHAli-eg7gz]

What kind of camera are you using? I love the setup. Thanks for sharing.

[@tornadoofthoughts]

how do you get to film "straight" (like if you were film directly with the camera) if you are poiting your camera to the mirror with some angle?

[@NasirAli-hs8np]

Thank you so so much for the beautiful and very informative video! May God bless you!

[@StudentCompanion]

Thanks for this video very informative.

[@maaifoediedelarey4335]

I realise this is an old (excellent!) video, but if uploader or anyone knows : What is (a) the optimum distance between the glass and the mirror, and (b) the size of the mirror relative to the glass? This is an excellent solution if one wants to livestream!

[@thomasbartley8336]

Do you really need the mirror? Can't you just flip the video in post-production?

[@eugeniovincenzo1621]

Yes, but you dont have to waste time post producing if you have a mirror...

[@eduardocosta9078]

The mirror is useful when you do a live presentation. That´s the case where the post-processing is not possible.

[@AdrianTschubarov]

@@eduardocosta9078 you can flip the screen in preferences or in obs

[@djmips]

@@eugeniovincenzo1621 He's admitting he does post-production in Adobe Premiere. A flip isn't a time consuming extra step at that point.

[@ankitbhurane5130]

How can I display computer screen on this while explaining? I need it for my lectures.

[@YoKai11722]

im just thinking about the mirror which you have used for flipping the image. what is the best position to shoot without camera actually intrusively visible in the shoot. i understand you kept it not perpendicular to the mirror, but then the view says it differently.

[@mytangolove]

Wow, amazing. Thank you for sharing.

[@nagesh007]

Amazing

[@arijitdas7526]

You can make the mirror image in premiere pro by flipping image horizontally.

[@CloudPower]

Great work, highly appreciate it.👍👍

[@pjavier]

I don´t know if somebody already asked this to you. But I want to know, how long is the distance between plastic glass to the mirror and the distance between the mirror and the camera? I know this depends on each case, but I want to have an aproximate distance in the case I want to built a dedicate room for this.

[@KimalHonourDjam]

Hello Jules, What type of glass are you using? Is plexiglass good because some authors feel otherwise? Would you please share your experience using plexiglass? Thanks

[@paulpadur2183]

I love the low cost solution. Have you had any issues with the scratches on plexiglass? What have you used to clean the surface?

[@jomaths1410]

I need help setting this up. How can get a technician build one for me?

[@andreykaok9497]

Fantastic! Thanks Jules.

[@mihaimolnar2880]

Hey man thanks for the tips. What camera do you use? I have an entry cam that has a stupid autofocus.

[@madara657]

hi awesome video. Just one question: What will happen if you use white backdrop and black marker? will your reflection be seen on the plexi?

[@doctari1061]

Just use ScreenFlowLive and flip the video in post production. Get rid of the mirror.

[@ihateteethsomuch3262]

flip horizontal in adobe after. mirror not needed

[@jeffs6232]

For everyone who is saying you can flip the video in post, you can do that, however, the issue becomes your writing hand gets flipped as well (i.e. if you're a righty it looks like you're writing left-handed and vice-versa). I believe the mirror eliminates this issue.

[@AnshuKaAayush]

does your right hand appears right when you look in a normal mirror?? just think before you say something bro!!!!

[@mister_allmond]

aayush paliwal yeah I’m not sure what dude was thinking lol

[@darkseid856]

Lol are you for real?

[@xAFKing]

why dont you just... flip the video horizontally in the render?

[@eduardocosta9078]

[@fruitcocktail64]

Hello! I built a lightboard with 6 by 3 starphire glass. I was wondering for plexiglass, if the thickness has to be more or less than that of glass. Thank you!

[@thinkingaloud1833]

Great series, very clear.

[@faisalkhan1026]

Awesome ! very insightful !

[@ramv9769]

Congrats- A good presentation can we project a Powerpoint PPT on this

[@jivanmainali1742]

Amazing setup

[@rakeshsabva6012]

Which marker to use????

[@MigueFinance]

could you please list the materials?, with amazon links, that would be of great help, thank you. Good Job BTW

[@AlbAlPasa]

Because Science’s setup made me search this tech. So cool.

[@CoopmanGreg]

Cool !

[@mufakkirhussain2816]

what will happen if i don't put black background or green screen

[@SweetPetite215]

This is great! What time of markers do you use? It seems like the ones my team uses squeaks a lot, which takes away from the learning experiences of the students.

[@theminertom11551]

Great video but I do have a question about the lack of visible imperfections in the plexiglass that you used. Used glass and even plexiglass have all kinds of imperfections. How come I do not see any here? I doubt that it is because the glass is so perfect.

[@StartupYogis]

Crush Black's in post production

[@ManuAnand79]

This is brilliant!

[@FILMUPDATES]

Hello sir I'm from India and I got Canon EOS 80 d camera can you please tell me the camera settings of and what I have to set please thank you in advance 😊

[@AlbertMaruggi]

so let me ask , is this better because during a live class you can respond to questions and annotate in real time?

[@danerose575]

Great! Thanks so much.

[@GilGuimaraesLima]

Good morning! What is the expecification of your glass? Thank you!

[@rishisnayak]

What is the exaxt name of the glass ? And how to clean it ?

[@balasubramaniam5516]

Hi, thanks for the video. I have a very important question. How do you clean/ wipe out the writings on the glassboard? Our glassboard has many smudges and marks on it now. Please help.

[@AnshuKaAayush]

use a car cleaning wiper for better cleaning

[@AyezaTarriq]

Thank you so much sir. which camera are you using?

[@On_My_Way_2023]

Really helpful

[@AlbertMaruggi]

when you say edit together that's post production. If there was no post production then you'd just hit save or upload and that would be it.

[@MakarkinPRO]

is it hard to clear that markers in online translations?

[@muzamilahmed3127]

What if we use OLED technology with lightboard for digital diagrams and animation....

[@timlucas143]

Why would you have a mirror?, its so easy to mirror even a live video feed not to mention if you are just editing it in editing software its almost just a click.

[@farukm7627]

Thanks for this helpful video.

[@ExplorerSpace]

you actualy dont even need mirror. just use video editing software to flip the video footage. and thats it

[@kellymcmanus6024]

How do you guys erase the board after using it??

[@jennifertabor8519]

What lights did you use?

[@user-vr4vm1hg9e]

may I use simple glass, not plexiglass?

[@learnwithlindon2199]

Sir how can we add presentation from laptop to display on the light boards.

[@eugeniovincenzo1621]

This is awesome

[@joechauncey]

How thick is your plexiglass? Is .093 inches thick enough?

[@brandonbehringer492]

thank you for explaining to me how ar glasses work

[@AyezaTarriq]

Dear please tell me which camera and lense you are using to record this lecture? i'm stuck at selecting a camera and a lense. please reply

[@scienceuniversityuniversit7282]

Thank you so much!!!!!!!!!!!!

[@user-ij5gv6ji5b]

You still look like you have mastered the art of writing backwards LOL. Flipping the image horizontally in post instead of the mirror will increase video quality and shooting convenience. You could also try light yourself at a lower intensity (but still with diffuse light) in order to not interfere at all with the drawing.

[@larrywright7537]

Very Cool !!!

[@AlbertMaruggi]

so how much would you pay someone to build this studio? Or conversely what's it worth to you to walk into a studio that was ready for you to just teach, oh yeah just a point, probably not a good idea to use a black jacket, you blend into the back ground.

Sir u are using this blackboard ? Did u ever face copyright issue . If face where did u get the permission . Plzz help me out because i also using this technollgy to teach in india . Plzz tell me if any issue i am getting in future about copyright.
